Impatiens plant named Jasius

ABSTRACT

A new and distinct cultivar of Impatiens plant named Jasius characterized by its large pure white flowers; early, continuous and prolific flowering, medium green foliage, and compact habit with vigorous growth and excellent self-branching.

The present invention relates to a new and distinctive cultivar ofImpatiens plant, botanically known as Impatiens, and known by thecultivar name Jasius. The new cultivar was developed by me in Gensingen,Federal Republic of Germany through controlled breeding by crossing maleand female parents which are unknown at this time.

Asexual reproduction by terminal cuttings taken at Gesingen, FederalRepublic of Germany, has shown that the unique features of this newimpatiens are stabilized and are reproduced true to type in successivepropagations.

The following characteristics distinguish the new impatiens from bothits parent varieties and other cultivated impatiens of this type knownand used in the floriculture industry.

(1) Large, pure white flowers.

(2) Early and prolific flowering, with white flowers at times coveringmuch of the plant surface.

(3) Large, medium green leaves.

(4) Plant habit is compact, but growth is vigorous and self-branchingexcellent.

The accompanying colored photograph is a top perspective view of the newcultivar, showing color as true as it is reasonably possible to obtainin a colored reproduction of this type.

The following is a detailed description of my new impatiens cultivarbased on plants produced under commercial practice in Encinitas, Calif.The described characteristics were noted between Dec. 10-20 and werebased on unrooted cuttings rooted under intermittent mist and thentransplanted into 6" pots, with flowering commencing in November. Colorreferences are made to The Royal Horticultural Society Colour Chart(R.H.S.), except where general terms of ordinary dictionary significanceare used.

Parentage:

A. Type cutting.--tip, with stems 2-3 cm long developing to 4-5 cm after21 days following propagation.

B. Time to initiate roots.--8-10 days at 23° C.; nicely developed rootmass in 18-21 days.

C. Rooting habit.--Numerous, fibrous adventitious roots from the stem.

Plant description:

A. Form.--Symmetrical, bush shaped, flowering herb, with self-branchingcharacteristics giving the plant a full appearance.

B. Habit of growth.--Vigorous, self-branching, medium habit, producingwhorls of leaves and flowers on branched stems. Growth is indeterminateand flowering is continuous.

C. Foliage description.--Leaves are simple. Lower leaves on stem areopposite. Higher leaves in whorls of mostly 5. (1) Leaf shape: ellipticto lanceolate, tip acuminate, base attenuate. (2) Leaf blade size: 11-13cm long×4-5 cm wide. (3) Leaf margin: ciliated and lightly serrated. (4)Leaf texture: (a) Upper surface: glabrous. (b) Under surface: glabrous.(5) Leaf color: medium green. (a) Upper surface: darker than 137A. (b)Under surface: near 137C. (6) Venation: pinnate.

Flowering description:

(A) Flowering habit.--Very floriferous. Flowering continuous. Flowersdevelop progressively around the whorl of leaves, taking 5-7 days frombuds which show color, to bloom. Flowers are single and large, lastingfor 2-3 weeks.

(B) Natural flowering season.--Flowering is indeterminate and occursthroughout the year. Quantity of flowers increases with increasing lightintensity and duration.

(C) Flower buds.--Ellipsoidal and covered with 5 sepals. Agreenish-white approximately 5 cm long spur originates from the base ofthe major sepal. Two additional, rudimentary sepals are fused to back ofthe top petal and sepals on either side of the pedicel.

(D) Flowers borne.--Singly, on pedicels 5.5-6 cm long; pedicels greenishin color.

(E) Quantity of flowers.--Floriferous. One or two flowers per leafoccurring progressively around the whorl of leaves so that tight buds tomature blooms are visible at the same time in large numbers.

(F) Petals.--(1) Number of petals: five (5). (2) Shape: Top petal heartshaped with wide base, all other petals heart shaped with pointed base.All petals overlap. (3) Color: pure white. (a) Upper surface: whiterthan 155D. (b) Under surface: whiter than 155D. (4) Size of flowers: 5.5cm across.

(G) Reproductive organs.--(1) Stamens: Five (5) with the lower stamenbeing shorter than the other stamens. Stamens are united in anasymmetrical tube surrounding the ovary. (2) Anthers: Hooded, white. (3)Pollen: Cream color. (4) Stigma: Five pointed star, colorless. (5)Styles: Very short, green in color. (6) Ovary: 5 celled, 4-5 mm. longuntil fertilized, green in color.

I claim:
 1. A new and distinct cultivar of Impatiens plant named Jasius,as illustrated and described.
